HRQOL Data Analysis Pooled Across Multiple Trials
OPPORTUNITY
Our client wanted to understand if their oncology product extended time to deterioration in patient-reported health-related quality of life (HRQOL) in 3 different tumor types using data collected across 4 clinical trials.
CHALLENGE
Individual trials that examined time to first deterioration in HRQOL using only patient-reported outcomes data found no difference between the client’s product and placebo groups.
OUR APPROACH
As side effects typically occur in the first few cycles and can potentially be managed with dose modifications, our approach was to reexamine deterioration in HRQoL using time to definitive deterioration. This deterioration definition accounts for the pattern of early declining HRQOL that may resolve.
